2 Claims. 1

The present invention relates to electrical cables and more particularly to cable connectors for storage battery terminals. I

The primary objects of the instant invention are to provide a device of the general character above indicated by which a storage battery terminal connector may be readily, conveniently and expeditiously secured to an electrical cable; to provide such a device which is highly eflicient in its intended use; and, to provide such a device which is reasonably economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawing, wherein:

Figure l is a fragmentary plan view of an electrical cable and the storage battery terminal connector;

Figure 2 is an enlarged side elevational view of the connector per se, partly in longitudinal section;

Figure 3 is a view similar to Figure 2 but showing the wire strands of the electrical cable in secured position with respect to the connector;

Figure 4 is a sectional view on line 4-4 of Figure 2; and

Figure 5 is a sectional view on line 55 of Figure 3.

Referring then to the drawing wherein like parts of the device shown are designated by the same numerals in the several views, the electrical cable of conventional type comprises a plurality of Wire strands l embraced within insulation sheathing II, one end of which cable is fixedly secured to the connector, generally designated I2.

The connector per se of any suitable metal such as lead alloy and preferably having a brass insert within its cable receiving well l4 comprises a conventional storage battery terminal gripping end adapted to be detachably secured to a storage battery terminal, not shown.

The opposite end of the connector provided with the longitudinal cable receiving well M has the inner wall of its well provided with a boss I! here shown as a generally arcuately formed flange intermediate its length, which boss is in registering spaced relation to a transverse internal depression l8 here shown as a generally arcuately formed groove or recess (Figs. 2 and 4) The outer length of the cable receiving end of the connector is provided with a pair of oppositely disposed, outwardly projecting anvils I9, 20, the anvil I!) being disposed opposite the boss I1 whereas the anvil is disposed opposite the internal depression I8.

In fixedly securing the cable to the connector,

the bared ends of the wire strands l0 and a portion of the insulation sheathing II are inserted within the well l4 after which when either of the anvils I9, 20 are seated upon a rigid surface, the other anvil is struck by a hammer or the like to compress and thus secure the strands I0 between the internal flange or boss I"! and the spaced registering depression or groove or recess l8, all as best viewed in Figures 3 and 5. It will be understood of course that either the flange I! or the recess 18 may be dispensed with and that either anvil l9 or 20 may be likewise dispensed with and further that in instances wherein one anvil is omitted, the anvil which is employed may be on the wall of the connector I2 opposite the wall of the well l4 whose inner surface is provided with either the flange I1 or the recess l8.

It will thus be seen that the storage battery terminal connector herein shown and described may be readily, conveniently and expeditiously secured to an electrical cable, that the same is highly efiicient in its intended use, and is reasonably economical in manufacture.

While but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted Without departing from the spirit of the invention as the same is defined in the following claims.

I claim:

1. A cable connector having a continuous integral wall and a well therewithin adapted to receive the inserted end of a cable, a flange within the well and a recess therein in spaced registration with the flange, a pair of anvils on opposite outer walls of the connector, one anvil being disposed oppositely of the flange and the other anvil being disposed oppositely of the recess whereby a blow upon either anvil permanently stresses the adjacent wall inwardly to secure the end of a cable pre-seated within the well.

2. A cable connector having a continuous integral wall of generally circular cross section surrounding a well of substantially the same cross section adapted to receive the inserted end of a cable of circular cross section, an arcuate flange and recess at the inner sides of the wall disposed diametrically opposite to each other substantially midway between the ends of the well, an anvil on each of the opposite outer walls of the connector extending outwardly therefrom, and having generally parallel flat outer ends 10-,

cated outwardly beyond the adjacent outer sides of the wall, one anvil being disposed oppositely of the flange and the other oppositely of the recess, whereby a blow upon either anvil with the opposite anvil against a support stresses the wall adjacent said anvils into inwardly extending flat Wedge shapes, and the outer ends of said anvils are moved inwardly toward each other to be substantially in the same planes with the adjacent outer sides of the wall.

THEODORE J. GRYPMA.
